Sonic Mainnet Launch: EVM-Compatible, Verifiable 10,000 TPS, and Sub-Second Finality
We’re excited to announce the launch of the Sonic mainnet, a high-throughput, EVM-compatible layer-1 blockchain platform that offers developers attractive incentives and powerful infrastructure.
With up to 10,000 transactions per second, sub-second finality, and a native decentralized gateway to Ethereum, Sonic enables developers to create the next generation of apps while offering users the smoothest blockchain experience yet.
FTM holders can now upgrade their tokens to S on Sonic on a 1:1 basis using our upgrade portal and unlock access to Sonic’s diverse range of apps. Developers, continue reading to learn how to deploy your apps on Sonic and start earning.

Network Information
Use the following details to add Sonic to your Web3 wallet of choice.
- Network name: Sonic
- RPC URL: https://rpc.soniclabs.com
- Explorer URL: https://sonicscan.org
- Chain ID: 146
- Currency symbol: S
Upgrade FTM to S
FTM holders can now seamlessly upgrade their tokens to S on a 1:1 basis using the upgrade portal on MySonic. Here’s how it works:
- Connect your Web3 wallet to MySonic
- Enter the amount of FTM to upgrade
- Verify that you’re receiving the same amount of S
- Click Upgrade and approve the transaction
In just a few moments, your S will arrive on Sonic, and you’ll be ready to explore everything the ecosystem has to offer! If you're holding FTM on Ethereum or a CEX? Follow our migration guide.
For the first 90 days after Sonic’s mainnet launch, you can freely swap between FTM and S through this portal. After that, upgrades will only be from FTM to S.
MySonic Portal
MySonic is your all-in-one portal to Sonic, through which you can access:
- FTM to S Upgrade
- App Explorer
- Staking
- Governance (Coming soon)
Sonic Gateway
The Sonic Gateway is a decentralized bridge that facilitates token transfers between Ethereum and Sonic.
The bridging process consists of three steps:
- Deposit
Deposit your assets into the bridge, which takes around 10-15 minutes on Ethereum to achieve finalization and only ~1 second on Sonic. - Heartbeat
After your deposit is confirmed, your assets will be bridged at the next heartbeat, which are intervals that bridge user assets in batches to ensure gas efficiency. A heartbeat occurs at most every 10 minutes from Ethereum to Sonic and 1 hour the other way. You can pay a Fast Lane fee to trigger an immediate heartbeat. - Claim
Claim your bridged assets on the destination chain. That’s it! You’re now free to explore the Sonic ecosystem with your new assets.
As cross-chain activity grows, secure and trustless bridges have never been more important Unfortunately, many layer-1 and layer-2 bridging solutions still rely on centralized systems, leaving billions at risk.
The Gateway addresses these challenges through two methods: a fail-safe and true decentralization. The immutable fail-safe automatically unlocks users’ bridged assets on Ethereum if the Gateway stops transmitting heartbeats for two weeks. This ensures users can always regain custody of their funds in the highly unlikely event of a Gateway failure, protecting user assets under all circumstances.
Furthermore, Sonic’s own validator network operates the Gateway by running clients on both Sonic and Ethereum, which ensures that the Gateway is as decentralized as the Sonic chain itself and prevents centralized manipulation.
We’ll expand the Gateway beyond Ethereum in the future, enabling direct, decentralized access to native assets on many other chains.
Airdrop: Sonic Points
As part of the ~200 million S token airdrop, Sonic Points are designed to reward you for engaging with Sonic and interacting with apps on the chain.
Focused on driving meaningful user engagement, Sonic Points incentivize key activities like early adoption, long-term loyalty, asset ownership, and active participation across the platform's apps.
You can earn Sonic Points by bridging whitelisted assets to Sonic or using them within the ecosystem through eligible apps. Learn more on our official documentation.
Developers: Build on Sonic
Deploy Your App
Sonic gives developers the tools they need to build fast, scalable apps, with 10,000 transactions per second and sub-second finality, ensuring your apps are both fast and scalable.
With full EVM compatibility and support for Solidity and Vyper, Sonic works seamlessly with the tools you already know, like Chainlink, Safe, Pyth, Alchemy, and more. Plus, with features like Fee Monetization, you’ll have the incentives to innovate and succeed in the ecosystem.
Start by testing your contracts on the Blaze testnet, and when you're ready, deploy to mainnet. Dive in and see how Sonic can help bring your ideas to life!
Fee Monetization
Fee Monetization (FeeM) on Sonic rewards you with up to 90% of the network fees generated by your apps, providing a sustainable income stream. This allows you to focus on scaling your app and growing your user base without the constant pressure of fundraising or securing additional financing.
Inspired by Web2 ad-revenue models popularized by platforms like YouTube, FeeM ensures you directly benefit from the traffic your apps bring to Sonic. By prioritizing developer rewards, Sonic sets itself apart from many blockchains that offer limited incentives and focus primarily on value extraction.
FeeM is set to launch on Sonic shortly. Stay tuned for more information.
Airdrop: Sonic Gems
As part of the ~200 million S token airdrop, Sonic Gems are developer-focused airdrop points designed to reward apps for driving user engagement and innovation based on their performance on Sonic.
Developers can redeem these Gems for S tokens, which they can then distribute as rewards to their users. Gems empower apps to kickstart growth and sustain long-term user activity by incentivizing consistent interaction and participation.

Frequently Asked Questions
How do I upgrade FTM to S?
FTM holders can seamlessly upgrade their tokens to S on a 1:1 basis using the upgrade portal on MySonic.
Where can I buy or sell S?
You can acquire S on decentralized exchanges (DEXs) on Sonic. We're working with key centralized exchanges (CEXs) to make S available on their platforms.
Stay updated by checking CoinGecko and CoinMarketCap to find the DEXs and CEXs where S is listed.
What if I have FTM/WFTM on Ethereum?
Follow our migration guide.
What if I have FTM on a centralized exchange?
We’re collaborating with major exchanges to enable users to upgrade FTM to S directly on their platforms. Stay tuned for updates from the CEX where you hold your FTM. Alternatively, you can withdraw your FTM and upgrade to S through our upgrade portal.
What happens if I don't upgrade my FTM to S?
If you choose to hold your FTM on the Opera network and do not upgrade it to S, no immediate changes will occur. The Opera network is expected to continue operating as normal for the foreseeable future, and you'll still have the option to upgrade your FTM to S at a later time if desired.
However, to participate in the Sonic network—including governance, transactions, and more—you'll need the S token.
